The key idea of statistical literacy at level 8 is becoming a knowledgeable consumer in a data rich society.
At level eight students are working with a wider and more sophisticated range of reports, building on the work at level seven and including critiquing causal-relationships claims and interpreting margins of error. The range of reports includes polls, surveys, experiments and observational studies. Reports can be from a variety of sources including media, journal, and government reports.
This key idea links to the key idea of statistical investigations at level 8 and the key idea of probability at level 8.
This key idea develops from the key idea of statistical literacy at level 7 where students can work with data from a variety of statistically based reports.
